The application is also quite simple, if you met a number of conditions.
The display should be thoroughly cleaned and the room should be as dust reduced as possible when applying the film. When applying the protector, never completely remove the peel-off the protective film, but when applying the protective film.
Now the film itself:
It affects the brightness of the display in any way, and if you do not look closely at specific sites, it does not recognize the foil is applied.
My Cheaper TouchPen works beautifully without limitation.
Now for the small defect:
The first day, the film does not feel good, because the wipe is inhibited over the film. One might think that an anti-slide coating on it. But the rum again has something good. The display smeared not so fast, or you do not see the fingerprints. After a few days the passes, however, and the wiping over the film is like on the display itself, thereby fingerprints but also come back and you should always have a little microfiber cloth near in order to clean the film from fingerprints.
I would always buy the film and also know again!
